lMPROVEMENT IN SNAP-HOOKS.

T 0 all whom "it may concern:

Be it known that I, GEORGE HAVELL, of Newark, in the county of Essex andin the State of New Jersey, have invented certain new and usefulImprovements in Swivel-Hook; and do hereby declare that the following isa full, clear, and exact description thereof, ref erence being had tothe accompanying draw ing and to the letters of reference marked thereonmaking a part of this specification.

The nature of my invention consists in the construction and arrangementof a swivelhook, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation,referring to the annexed drawing, in which-Figure l is a side View, and Fig. tudinal section, of my swivel-hook.

A represents the hook provided with the usual stem or spindle passingthrough the bar or bridge B,to turn on the same. At the base of the hookA are cars a, between which the tongue 0 is pivoted. The tongue 0 andhook a longisuitable thickness rolled in the proper shape, or otherwiseformed in tubular shape.

This mode of construction makes the hook very strong, while at the sametime it is lighter and stron ger than the common swivel-hook.

Around the pivot which holds the tongue 0 between the cars a a is wounda wire-spring, b, the ends of which extend up, respectively, into thehollow'hook and hollow tongue, as shown in Fig. 2. The spring is thusentirely covered and shielded from all injury.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the hollow or tubular hook A, hollow or tubulartongue 0 pivoted between ears a a on the hook, and the spring I), havingits ends extending up into the hook and tongue, all substantially as andfor the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this30th day of April, 1872.
